“
I got these straight from Japan via Tenso right as Dsnuts got the hype train rolling last fall. Bought 3 pairs, of which I gave one to a colleague (yes,they are so inexpensive you can just give them away!) and one to my brother in law, and luckily, I kept a pair myself! I have an ongoing love-affair with these headphones! Higher end portables (Sennheiser HD 25-1 II, ATH ES700 etc.) has come...” --esmBOS

“
Tight competitor of GR07, this IEM isn't a replacement for GR07, but rather, a complimentary IEM.
How does it sound? Fun, thick, and musical. Not your best analytical sounding IEM, while it does bring out details nevertheless.
To me, it's a great buy, because I don't need anymore accurate sounding phones, but rather something fun and colored to my personal preference....” --autumnholy

“JVC HA-S680
This isn't a detailed review.
If you are still an S500 user and prefer it's sound, get the S600, to see why, read below.
I'm still kinda shocked nobody has voided people from these.

I got this headphones for CAD $59.99 at FutureShop. I bought this because I want a lightweight headphones that I could wear for a long period of time without making my ears/head hurts because I don't like wearing my Shure DJ headphones in public or in a long periods of time as it gets hot and uncomfortable. This headphones sounds really great for its price. I know, the sound is not as good as...” --adriel1392

“ I’m not going to waste your time talking about accessories, fit, packaging, what songs I listened to or any other boring stuff because frankly none of that stuff matters when it comes to the JVC HA-FX700’s. The only thing that matters is the unbelievably good sound coming from these, so without further adieu- The sound: MASSIVE. That’s the first thought that comes...” --shotgunshane

“I was looking for an inexpensive pair of on-ears and, after reading some positive reviews on the "flats", I decided to give them a try.
Packaging: simple as it gets. No accessories. Just the earphones in a plastic package.
Build quality: materials are on the cheap side, but with no major concerns. I have been using them for almost two years now, and they show no signs of...” --Mellowship

“ Introduction Having had extensive experience with the previous Wood series of JVC, FX500 and FX700, I was exited to see what the company had planned for this next iteration. They introduced FX650 to replace the FX500 and FX750 to replace the FX700, in addition to announcing the new flagship, FX850. Thanks to user James444, I was able to hear all 3 IEMs of this new...” --Inks

“The bass is very good for the price and the driver size. The sound however, could be improved further by equalization. The highs are suprisingly good but these headphones are lacking a bit of the mids. These headphones are very lightweight and comfortable, allowing up to long hours of use.
However, I can still remember the time I took these headphones out of the box, they sounded awful....” --ryanwee9889

“ Disclaimer #1: In my experience, I've come to discover that the term basshead is tossed around very loosely, and (more often than not) carries a negative connotation, when that need not be the case. Where I'm concerned, such terms must be put into context. As I've used it here, the term basshead merely implies a listener who admires (and/or maybe even prefers) a moderate to heavy bass lift....” --Night Crawler

“
I bought this headphone twice, because I like it a lot. They're good for the money, not perfect but definitely great. First, I'll talk about build quality and comfort, then efficiency and sound. (and also a bonus category of how moddable they are)
TL;DR review:
9.5/10 overall. Sound/value easily 10/10. Comfort 9/10. Build quality 8/10. Does not need amp, benefits from one....” --LaPierre
